Here's a few options:
Cigital is a great enterprise vendor. They come to you and will customize training for your particular shop. They're the high end option.
Security University offers a set of training packages. They're comprehensive but not custom. Sondra, the CEO, is one of the nicest people you'll meet in the industry.
SANS offers conference-like training options, where you go to them and sit in on several day's worth of training.
Aspect Security offers a smaller set of 3 day, conference like training options. Never dealt with them, but they make the rounds at conferences.
BlackHat, the conference, offers training sessions. Anyone teaching there will also be willing to sell you training.
Cigital, Security University, and Aspect Security also offer online courses. Maybe SANS too - don't know off the top of my head.
